They sure do, in particular the thin wire going from the power brick to the laptop, and specifically the part by the mag connector. The L shape connectors are a tad better than the T ones, but still, Apple has designed those cables too flimsy!

I have bought used adapters and they have worked as well as new ones, again it's really the thin cable part that gets kinked/bent and ultimately "breaks" and it's kind of deceiving because the cable can be broken on the inside of the plastic with little to no visual notice to you. But if you notice the little light on the connector not being on when you connect the mag part to the computer, you really need little more notice that the wire is probably broken in some spot, sure you can jiggle the mag connector (which in turn also moves the wires inside the cable, and get the thing to light up, but guess what...if you have to do that the cable is more than likely broken.

Apple does run sales on the adapter every so often (of course probably not when you need one) otherwise look on Craigslist, I've bought used ones from a guy up here who buys old computers and then part them out, and they have worked just fine.

It didn't break/burn at the pressure relief point. She pinched the cord in the middle on some furniture. I bought a used one on eBay for $22 or thereabouts. I was more interested if the brick itself burned out. I've had no problem (other than this mechanical break) with the two we have.

Thanks.
